- The greenhouse effect is defined as when the Earth's atmosphere becomes thick with gases and substances which trap the sun's radiation, making the Earth warmer.
An example of the greenhouse effect is global warming.
Industrial gases pumped into the air create a greenhouse effect.
greenhouse effect definition by Webster's New World
greenhouse effect definition by American Heritage Dictionary
- The phenomenon whereby the earth's atmosphere traps solar radiation, caused by the presence in the atmosphere of gases such as carbon dioxide, water vapor, and methane that allow incoming sunlight to pass through but absorb heat radiated back from the earth's surface.
- A similar retention of solar radiation, as by another planet or in a solar panel.
Energy radiated by the sun converts to heat when it reaches earth. Some heat is reflected back through the atmosphere, while some is absorbed by atmospheric gases and radiated back to earth.
greenhouse effect - Cultural Definition
A term used to describe the heating of the atmosphere owing to the presence of carbon dioxide and other gases. Without the presence of these gases, heat from the sun would return to space in the form of infrared radiation. Carbon dioxide and other gases absorb some of this radiation and prevent its release, thereby warming the Earth. This is an effect analogous to what happens in a greenhouse, where glass traps the infrared radiation and warms the air.
- The burning of fossil fuels adds carbon dioxide to the atmosphere, and therefore places the Earth at risk from an increase of this effect.
